SANITARY COOLER.

Application alec March 2o, 1923. serial No. 626,426.

To all whom t may con-oem:

Be it known that we, HARRY K. BUSH and BLRTOLET F. FRAME, citizens of theA in water coo-ling apparatus and more particularly to devices adapted for installation in workshops, factories, offices and dwellings.

@ne of the objects of the invention 1s to provide an apparatus inthe form of a tank containing in plurality of the units so arranged as to use ice in an extremely advantageous and economical manner.

A further aim is inthe provision of a cooling unit readily and completely separable for the purpose Cif-cleansing the interior as occasion requires, and lined to present an enamelled surface for sanitary purposes.

These several aims, objects and purposes are accomplished by the novel construction and arrangement of parts hereinafter described and illustrated inthe accompanying drawing, forming a material `part of this disclosure, and in which V Figure l is a longitudinal sectional view taken through the dispensing tank, showing the relation of parts therein.

Figure 2 is a longitudinal sectional view of one of the cooling units drawn to an enlarged scale.

Figure 3 is a top plan view of the lower elements of the cooling unit in detail.

Figure 4 is a bottom plan view of the upper element and delector.

Figure 5 is a plan view of the device drawn to a smaller scale.

As shown in the drawing, particularly Figure 1, the tank will be seen to consist of a rectangular, box-like structure generally designated by the numeral 10, having a bottom or flooring 11, and a readily movable cover 12, for the reception of blocks of ice 13, the same being disposed upon the upper surfaces of the several cooling units con-v tained in the tank.

These cooling units each consists of a conical casing 14, the smaller end of which is directed upwardly, its walls integrally connected by a plate element 15, in one part of which is a depression 16, curved at its bottom wall 17, and having a vert-ical wall 18 drilled and screw-threaded` to re' ceive a pipe o-r nipple 19. Y

The end of the nipple enters a space 20 formed in a central internal vhub or lug 2l-screw-threaded in its lower end to receive a pipe 22 which extends downwardly nearly to the bottom of the conical casing and has attached at its lower end a `dei'iecting plate 23 having a raised` marginal edge 24.

The lower, larger end of the casing-14 isr turned outward to produce a beaded edge 25 suited to enter within an annular flange' 26, formed with the base or bottom element27 which rests upon the fico-r 11 of the tank. j

The lower portion of the cup-shaped base 27 is formed to present an annular downwardly curved projection 28 raised at the center 29 and provided internally with a series of upstanding ridges orvanes 30, arranged to receive water froni'the pipe 22, distributed by contact with the centerprojection 29 and thereafter cause it to deflect raised vanes 30.

Ultimately the water rises past the curved j edges 2/1 intothe upper portion of the unit, which isprovided with an internal lateral hub 31 to receive a discharge pipe 32, that may be joined by a union 33 to others in series, the last ofv which yhasl its outlet a header 34 and discharge pipe 35 extended through the wall of the tank as shown.

Preferably there are eight units in each tank, arranged in two rows and connected by a header 36 engaged with the inlet 37.

Formed with the upper elements are projecting lugs 38 containing openings 40, similar openings 4t2 being formed in like lugs 39 extending out from the lower elements 27, these openings being in register so -as to be connected by bolts il having nuts l1:3 adapted to clamp the upper and lower elements rigidly together, there being interposed between their adjacent faces packing rings' or. gaskets 44;.

In operation, water entering the inlet 37 passes through the first pair of cooling units, and from thence to the intermediate units, eventually being discharged through the pipe 35.

As the water enters each unit it strikes upon the raisedcentral element 29, is diverted by the curved vanes 3() and the dei'lecting plate 23, thus creating an effective circulating system.v

As the blocks of ice rests on top o'f several units it is not necessary to break the ice into fragments for the purpose of cooling the' materiale of nonfcorro'sive nature,wit will beseenthat cool water in aiclean'hygienic condition. can .be Withdrawn at any timedesired, anddue to the relatively large area presentedbyy the several units, a correspondingly` large quantity can be brought to the desiredA temperature. without. loss .of time, a constant flow being accomifnodated'v in actual practice- As changes `of construction could bei madewithin. the scope of the invention, itis intended thati all matter contained inthe foregoing description or shown in the accom-v panying. drawing shall be interpreted as il lustrative only and notinfa limitative sense. Having. thus described our. invention, what we claim as new and desire to secure' by Letters Patent, is:

1. A cooler. comprising a tank, a series of communica-tingicooler units havingl a central` inlet tube open at its lower. end, andf avbot tomiclosure for. each un'it. having radiating spiral grooves receptive of the fiuidpassing through the tube and causing a rotary effect thereto.

2. Iny a cooler, a unit comprising a hollow rusto-conical casing closed at its smallery upper end andv having a beaded edge at its lowerend, a' base receptive of. said edge,;a

packing interposed therebetween, means for clamping said casing to the base, an annular recess of semi-circular cross section in said base presenting a raised central portion, a

' tube extending axially downward in said casing from the closed end terminating ad] a-= cent the central raised portion of the base, a lateral inlet to said casing communicating with saidtube, and an outlet opposite thereto.

3. In a cooler, a unit comprising a frustoconical casing, a cup-shaped base removably engaged therewith, said base having a central raised portion, a tube directing an entering stream of fluid: upon said raised portion, and adeflector secured onf said tube above said base, said deiector havingl an upturiied peripheral edge disposed closely interjacent the wall of said casing.

il.A In a cooler,.a unit comprising a conical casing, a cup-shaped base removably engage'dtherewith, said base having a centra-l raisedpor-tion, means-:tor directing anf entering stream of Huid upon said raised portion, means in said basetocause a whirling e'ect of the entered liquid, and a detlector plate secured to said liquid entering means adjacently above said base.

5. In a ccolei;,.a unit coniprisingaconical casing,` a cup-shaped base removably engagedI therewith, said.` base havingj av central raised portion, means for directing an enter.``v ing stream off fluid upon saidraised portion, a tube depending axially in saidcasing, there beingA aI lateral inlet? communicating vtherewith,a defiecting plate fixed onthe end of said tube spaced.I above said base, anda-plu rality of curvedi'ridges inthe cavityv of saidbase adapted to'cause liquid'enteringtlirough said tube to assume a whirling inotionbelow said delectingy plate.

Intestimony whereof we have signed our names to this application.
